SPECIFICATION forming* part Of Lttel Patent NO. 630,917, dated August15, 1899.

Application filed April 9, 1898. Serial No. 677,062. (No model.)

To all whom, it may con/cern:

Be it known that I, EDWIN C. MOFARLAND, of Melrose, in the county ofMiddlesex and State of Massachusetts, have invented a new and usefulImprovement in Type-Molds, of which the following is a specification.

In making type, more especially type ofthe larger sizes, it is desirableto relieve the finishers from as great a proportion of the finishingwork as is possible. type has been taken from the mold it has been stillnecessary to prepare the groove so as to properly finish the bottom orfeet of the type and to remove the jet. This has been a matter requiringconsiderable care and corresponding expense in the employment of skilledlabor, as Well as considerable time. My invention is intended to do awaywith the Agreater part of this hand-work and produce in the mold a typewhich shall be substantially iinished and, especially in the largersizes, shall be materially lighter in Weight than those generally cast.Moreover, a type cast in the best form of my mold will be more perfect,for the reason that in such a mold the stream of metal may be adjustedin size and also directed to one side or the other of the mold-cavity,according as the shape of the matrix requires more or less metal on oneside or the other to till it or so that it may strike a counter-in thematrix, and thus prolong the life of the matrix.

My invention consists in providing the mold with a core shaped to formthe groove in the bottom of the type and adapted to be moved in a planeparallel with'the matrix and in contact with the entrance-wall of themold, so that it may be withdrawn from the mold when necessary-forexample, just after the metal has set and before the mold is opened, sothat the newly-cast type may easily drop out from the cavity. As thefaces of the larger-sized types, because of their design, often requiremore metal on one side than ou the other, it is desirable that thestream of metal shall so iiow into the mold-cavity as to insure thecomplete filling of the corresponding cavity in the matrix. The coreshown has an opening through which the stream of metal will iiow intothe mold-cavity, and by making the core movable in the mannerdevHeretofore after the scribed the force of the stream may be thrown toeither side of the mold-cavity, as thought best, and by adjusting thelength of the opening the size of the stream may be adjusted.

My core is made, preferably, in two pieces, a portion of the core beingslotted, and as the core-pieces abut they form practically a single corewhich is adjustable both as to the location and the size ot' the streamof metal. If 6o the slot is short in proportion to the width ot' themold-cavity, the change in its position will change merely the locationof the stream. n If long, a greater or less portion may lie within theentrance of the cavity to form an entrance for the stream.

My invention will be understood by referenceto the drawings, in which--Figure 1 is an elevation of the mold embodying my invention, the matrixand various attaching parts being omitted. Fig. 2 is a horizontalsection on line 2 2 of Fig. l, the matrix being in place. Fig. 3 is across-section of the mold-cavity, the matrix being in position. Figs. 4and 5 are elevations of the mold-cavity, the matrix being removed, show`ing diierent adjustments of the core. Fig. 6 is a perspective View ofthe product of this mold. Fig. 7 is an elevation of the mold open forthe ejection of type, the matrix being omitted in order that therelative position of the cores may be understood.

A is the top section of the mold, and B is its bottom section. They arepivoted together' at C in the usual manner. The mold-cavity is indicatedat D and has an entrance E in its rear through which the stream of metalis forced into it from the metal-pot.

F is the space in which the matrix G is set, the matrix being clamped inthe usual manner at the sides and top bythe clamps H, H', and H2, itsbottom being also supported in the usual manner. (Not shown.) l

From the upper part of the mold A projects an arm J, carrying twohangers. One of these hangers j serves as the support for the rear endof the rod K, upon the front end of which is mounted a core-piece L,which slides in a suitable opening in the top section of the mold,having a tight sliding fit therein and being suiiciently long to get aneasy bearing therein. This core-piece is somewhat nar- IOO rower thanthe vertical Width of the moldcavity, as will be seen from thedrawings,`and is forked at its front end to form a slot or jetopening Z.The rod K is provided with two adjusting-collars 7c 7s', which may beset to limit the throw of the core-piece.

It is desirable, of course, that the corepiece L shall have a movementin a straight line at right angles to the entrance-wall of themoldcavity. For this purpose a handle K' is provided, which is pivotallymounted upon the hanger j, carried by the arm J. As the movement of thefront end of the handle K will be in the arc of a circle it should beattached to the rod K by any one of a number of forms of pivotalconnection providing for lost motion, such as are well known tomechanics. I have shown, in fact, a short sleeve held to the rod K by aset-screw, and to this sleeve the forked end of the handle K' isattached by a slotted connection.

The bottom section B of the mold is provided with an arm M, carrying asupport m for the rear end of the rod N, and a second pivotal support mis provided for the handle N', which is attached to the rod Nin the samemanner as the handle K is attached to its rod K and for the samepurpose. Upon the rod Nare also carried adjustable collars n n', whichlimit the stroke of the rod N. At the front end' of this rod N iscarried a second core-piece P, which, as shown, diers from the firstcore-piece L in being solid instead of forked, but otherwise is ofexactly the same dimensions and slides in a groove in the bottom sectionof the mold, in which it has a sliding fit. The two grooves referred toform a continuous passage of uniform size, so that the core may slideeasily therein.

The hangerj, as shown, is a clamp-il e., a split bearing-which straddlesthe shaft and is provided with a clamp-screwjz, which may be tightenedso that the jaws of the bearing may be brought together to clamp the rodK in any desired position-as, for example, while the casting operationis taking place. A similar clamp m2 is carried by the arm M Y and servesby means o'f the clamp-screw m3 `place of the cores.

to clamp the rod Y.

To operate my mold, the matrix being in place, for example, as shown inFig. 3, the desired position of the core is first determined in orderthat the jet-opening Z may properly admit the stream of metal, accordingto the letter or character to be cast. Three positions of thejet-opening are shown (see Figs. l, 4,

and 5) to illustrate the adjustable feature of my invention, theadjustment being made as the operator thinks best under the givencircumstances. In any case the opposing ends of the core-pieces are incontact When the cast-ing is -to take place. After the position ofthecore has been determined the collars 7s and a are set to limit theforward throw of the core-piece and so determine the meeting The collarsk 'a' are adjusted so that the cores may be withdrawn sufliciently farto leave themold-cavity free.

The matrix being in place the mold is now ready for use, and the coresare thrown into the mold-cavity as far as they can go and so that theiropposing ends are in contact, and they are clamped in that position bymeans of the clamp-screws j? m3. The casting operation then takes placein the usual manner, the metal passing through the entrance E and slotZ. The core being narrower than the rear wall of the mold-cavity willallow the metal to flow against the upper and lower portions of thatwall to form the feet of thetype. (See Fig. 3.) The clamp screws ,7'2 m3are then tu rncd to release the core-pieces,and the corepieces arewithdrawn by the handles K N' and the mold opened to throw out the type.

The adjustable feature of my core is useful where, as is almostuniversally the case, the

mold itself is adjustable, 'and while I have shown two movablecore-pieces forming'for cast-ing purposes a single core it isevi-dentthat if one of the core-pieces is rendered stationary, with its faceinthe same plane with the wall. through which it moves, the other orforked core-piece may be moved up against it, thus forming, in fact, asingle core, which will answer all the purposes in many cases of the twocore-pieces which I prefer to use. Moreover, the jet opening may beVmade shorter than shown, the location of the incoming stream in thiscase being adjustable rather than its width. This is desirable, becausewh ere, for example, a large ornamental type of a decorative characterhaving a number of tine lines upon it is to be cast the type is verymuch more accurate and sharply defined where the metal is thrown fromthe entrance'directly into that part of the matrix which is to formthese lines.

)Vliere two core-pieces are used, as shown, their direction of movementinto and out of the mold-cavity is immaterial so long as when in placethey will form a core having the characteristics described, and theshape of the abutting ends of the core-pieces andthe plane in which theyunite is also immaterial so long as they correspond, my purpose being toso IOO shape the ends of the core-pieces that when together within themoldcavity they will form a continuous core.

The product of this mold will be a type which will have thecharacteristics indicated in Fig. 3, where such a type (marked Q) isshown in section-namely, a type having a groove cast in it, from whichmay project a slight jet which is easily removable, leaving possiblyaslight bur which requires but one finishing operation to clean off. Thefinished type is shown in Fig. 6, the jet having been removed, and thegroove serving not only to lighten the type, but'also to finish thefeet, without further manipulation.
